+// The generated file contains four major function templates
+// (in variants for arbitrary numbers of arguments up to 10,
+// which is why it is machine generated). The four templates
+// are:
+//
+// WrapTask(o, m, ...) -- wraps a member function m of an object ptr o
+// WrapTaskRet(o, m, ..., r) -- wraps a member function m of an object ptr o
+//                                  the function returns something that can
+//                                  be assigned to *r
+// WrapTaskNM(f, ...) -- wraps a function f
+// WrapTaskNMRet(f, ..., r) -- wraps a function f that returns something
+//                                 that can be assigned to *r
+//
+// All of these template functions return a GMPTask* which can be passed
+// to DispatchXX().
